The Neck is an example of a 1st class lever Load-Fulcrum-Effort. The entire head is the load. The joint between the skull and spine is the fulcrum. Lastly, the muscles at the back of the neck provide the effort.

For the second image, the ball of the foot is the fulcrum, the weight of the body is the load, and the calf muscles provide the effort. This is an example of a 2nd class lever Fulcrum-Load-Effort.

The fulcrum is the elbow joint, the effort is the bicep (which inserts after the fulcrum) and the load is the weight of the hand or anything being held. The bicep is an example of a third class lever Fulcrum-Effort-Load.

Modifying your home or workplace to enhance accessibility, safety, and independence.

Examples:

Grab Bars/Handrails: In bathrooms, hallways, and staircases for fall prevention and to provide safety.

Non-Slip Flooring/Rugs: To prevent falls.

Activity Modification: sitting while showering

A shower chair to use in the shower while bathing that allows you to sit while showering incase of weakness or low endurance. It is also a good assistive device to use when transferring from a wheelchair to the shower as there is a removable arm rest and extra room to transfer.

Wearing clothing with Velcro instead of ties or buttons. This simplifies dressing and reduces the need for fine motor skills. It can be quite a task to bend and tie your shoes and increase fall risk. But you can increase independence and conserve energy by using simplified clothing.

Ergonomics

Using an adjustable monitor stand in order to help keep your neck and spine in a neutral position, not flexing or extending your neck. This will help counteract tech neck.

Ergonomics are important in maintaining healthy biomechanics. Ergonomic adjustments and devices like standing desks, foot rests, proper chairs, etc. prevent injuries, pain, and fatigue, maintain good posture, and promote comfortability.

Modifying an activity means adjusting how you do it to reduce difficulty, improve safety, and minimize physical strain. This might involve dividing tasks into smaller steps, managing your pace, or using specialized equipment.

Assistive devices/ technology

These are different keyboards for people experiencing things like carpal tunnel or who are having trouble with their vision.
